Analytical expressions for general rogue waves in the NLS equation have been derived in [1]}, [2]}, [3]} by various methods. However, those expressions are not the best for our solution analysis. Here, we present a simpler expression for these solutions, which can be derived by incorporating a new parameterization [4]} into bilinear rogue waves of Ref. [3]}. These simpler expressions of rogue waves are given by the following theorem.
